Problems solved by technology

However, Lentinus edodes belongs to medium and low temperature type temperature-changing fruity mushrooms. The optimum growth temperature for mycelia is 24-27°C, and the optimum temperature for fruit body development is 8-20°C. If a higher ambient temperature is encountered during production, it will often cause Mycelial death and rod rot

Embodiment 1

[0046] Example 1. Breeding of high temperature resistant lentinus edodes strain-lentinus edodes 16×kou 46

[0047] The main summer cultivars of Lentinus edodes No. 8 (referred to as Gaotian No. 8) and Lentinus edodes Kouxiang (referred to as Kouxiang) were selected as the parent strains for cross breeding of high-temperature resistant Lentinus edodes hybrid strains. details as follows:

[0048] 1.1 Test strains

[0049] Parental strains: Shiitake No. 8 and Shiitake Kouxiang, select the round shape, 7-point mature parent fruiting bodies to collect monospores.

[0050] 1.2 Isolation and identification of monospores

[0051] The parent fruit body is suspended in a triangular flask filled with sterile water for 3-5 days, diluted and spread on a PDA plate, cultured at 25°C for 3-5 days, picked out a single germinated colony and transferred to culture, and observed under a microscope for locks joint. If there is no lock-like association, it can be preliminarily considered to be a monocytic...

Abstract

The invention discloses a high temperature resistant Lentinus edodes strain and a cultivation method thereof. The registration number of the high temperature resistant Lentinus edodes strain is CGMCCNo. 18565 in the China General Microbiological Culture Collection Center. Lentinus edodes Gao 16 * Kou 46 is a hybrid strain which is bred by crossing Lentinus edodes High Temperature No. 8 and Lentinus edodes Kou Xiang as parents, can be fruited in a high-temperature environment and has better agronomic traits than Lentinus edodes High Temperature No. 8 and Lentinus edodes Kou Xiang: the fruitingtime is earlier than the fruiting time of Lentinus Edodes High Temperature No.8 and Lentinus Edodes Kou Xiang; the weight of single fruit body was higher than that of Lentinus Edodes High TemperatureNo. 8 and Lentinus Edodes Kou Xiang; the thickness of the fruiting body cover is higher than that of Lentinus Edodes High Temperature No.8 and Lentinus edodes Kou Xiang; the carbohydrate content of the fruiting body is higher than that of Lentinus edodes High Temperature No. 8 and Lentinus edodes Kou Xiang; the essential amino acid content of the fruiting body is higher than that of Lentinus edodes High Temperature No. 8 and Lentinus edodes Kou Xiang; and the yield of the fruiting body is higher than that of Lentinus edodes High Temperature No. 8 and Lentinus edodes Kou Xiang.

Description

Technical field [0001] The invention relates to a high temperature resistant mushroom strain and a cultivation method thereof in the field of biological breeding. Background technique [0002] Lentinula edodes is a saprophytic fungus produced in the temperate and subtropical regions of the northern hemisphere. It is not only rich in nutrients, but also has high health value, and has been loved by people since ancient times. However, lentinus edodes is a medium-low temperature type variable temperature fruiting mushroom. The optimum temperature for mycelial growth is 24-27℃, and the optimum temperature for fruit body development is 8-20℃. If high ambient temperature is encountered during production, it will often cause The hyphae die and the sticks rot. The cultivation season of shiitake mushrooms in most parts of China starts in autumn and lasts to the spring of the second year. Therefore, during the high temperature season in summer, there is often a low season of market supply...
